ORP probe or PH?: it looks like a ORP probe but comes up as PH in fusion

[mebeknob]

Purchased used APEX and the ORP (I think) looks a bit old. I don't have saltwater yet, just fresh for Apex setup so the numbers are misleading. So the readings for both PH probe and ORP (PH2) are between 6 and 9.
Also the ORP (PH2) probe comes up as PH on fusion.


Did Neptune ever have a red PH probe?
If not what is going on?

You need to change the ORP/pH2 port to be in ORP mode. Do that using the Classic Dashboard, Probe Input Set page. Enable ORP, and pH2 will become automatically disabled.

Thanks @RussM! I changed the setting and my ORP tile came up and the PH2 went away.
It is currently showing 0. Does it just need time before it starts reporting out?

It has been 3 days and it is now reporting out 0.

Is this a sign of a bad probe?
